In order to contribute to and assure sustainable ambitions in the design process of utility buildings, a framework was developed. This framework the ‘STODUR’ enables parties from all levels to discuss the subject of sustainability. In the framework attention is given to the strategical- and tactical aims of sustainability in a building project. Furthermore, the operational (direction of) solutions are linked with the tactical aims, thus giving insight and overview to all parties involved. Sustainability can be defined as a personal judgement, which reveals itself in variety of different approaches, on how to, as well as to the extend to which properties and features of the built environment minimize the negative impact and maximise the positive impact on existing environmental problems (deterioration of the human health, deterioration of ecosystems, depletion of resources); the considered level of scale, time and the scope of measured properties are determined by that personal judgement. The framework should contribute to the ability to discuss sustainability and its aims, and to help solve several problems, such as confusions on the topic (due to its personal character) and the loss of focus. ; Design and construction management ; Real Estate & Housing ; Architecture
